“Date of incident : August 31,2025 Around 9pm on August 31, I was fixing to accelerate at a green light. I pressed the gas pedal, my car went up to 40 mph and then the engine failed. This is due to a recall on the bearing rods for 2015-2020 Acura TLX. The incident occurred a month after financing the car. I don't have a warranty, so I opened up a case with the manufacturer to get help with the repair cost (which is 25,500 for a new engine block and 2 new cylinder heads). Unfortunately, Acura denied assistance. The car only has 68880 miles on it. …”

She stated to me that she pushed the P(park,) but unfamiliar with my car and doesn't know which buttons on the panel are such as P(park,) R(reverse,) N(neutral.) With that said let it be noted that when I bought the car in April of 2022 the D & P were worn out from use. …”
